The RSA: A Professional-Grade Putting Calibration Instrument

What is the RSA?

The RSA stands for Roll & Speed Analyser. All RSA devices are machined aluminium putting training aids designed to isolate start-line accuracy and calibrate green-speed perception. Engineered by Engineers,Tour coaches and Tour caddiess, it serves as a "Source of Truth" to distinguish between a technical stroke error and an incorrect green read.

Key Performance Specifications

• Material: Machined Aluminum (Anodized)

• Launch Geometry: Proprietary brachistochrone-inspired geometry engineered to minimize skid and accelerate the transition to forward roll.

• Calibration Scale: Vertical metric scale (1-30) for repeatable speed/force control.

• Portability: Dual-hinged "Fold-and-Go" design (fits in standard tour bag apparel pockets).

How does the RSA improve Strokes Gained: Putting?

In professional golf, the margin for error on the green is nonexistent. The RSA.30 was engineered for the elite player who understands that improving performance requires mastering two variables: Start-Line Consistency and Visual Calibration.

1. Eliminating the "Guesswork" in Green Reading

Whether preparing during an off-week training block or dialing in performance ahead of competition, the RSA ensures your “feel” is supported by physics. The high-rigidity machined aluminum construction produces consistent launch conditions that eliminate stroke variability, allowing players to isolate whether a miss resulted from the stroke or the read. If the ball misses, the feedback is immediate — the read was wrong, not the stroke.

2. Solving the "Tournament-Week Problem"

Tour players often struggle to adapt quickly to varying Stimpmeter speeds and grass types (Bentgrass vs. Bermuda) from week to week.

• The Workflow: our team designed the RSA to solve this calibration lag.

• The Result: Spend just five minutes on the practice green with the RSA to calibrate the speed. Players quickly develop a reliable feel for how fast the greens are rolling, eliminating the first 2–3 holes of guesswork that can cost even elite players shots.

3. Professional-Grade Engineering vs. Consumer Aids

Most training aids are built for the mass market; the RSA is built for the professional environment.

• Tour Experience (Douglas Wood & David Buhai): As a Professional Tour Coach & Professional Tour Caddy, Wood & Buhai ensured the RSA functions as a diagnostic tool, isolating aim from the actual roll of the green.

• Computational Precision (Deon Du Plessis): Our founder applied computer engineering science principles to eliminate variables. Unlike plastic ramps that flex or warp in the sun, the machined aluminum build provides laboratory-level consistency in any climate.

Technical Comparison: RSA vs. Traditional Methods

Why Elite Players Choose the RSA

Elite players search for tools that offer reproducibility. The RSA delivers this by quantifying the "feel" of a putt.

• Off-Week Quality: Stop hitting mindless putts. Use the metric scale to build a library of "feels" for different slopes and speeds.

• Tournament Efficiency: The "Fold-and-Go" design means your most important diagnostic tool is always in your bag, ready to provide the "Source of Truth" on any green in the world.

Our Mission: Kill the "Guess Work"

We believe that "feel" is what you have left over after you’ve measured everything else. The RSA turns "guessing" into "knowing."

Built by the Tour. Used by the Elite. Engineered for the Truth.
